skeptical inquiry

Apophenia: A natural psychological tendency in which patterns are discenred in random information, apophenia is the basis for other perceptual phenomena, such as pareidolia, auditory matrixing, confirmation bias, and divination. Critics of EVP frequently rely on apophenia as a catch-all explanation for why listeners identify anomalous voices in the audio medium and see ghosts in the photographic findings. Conscientious paranormal investigators, however, are vigilant self-observers and use skeptical thinking and the peer review process to avoid incidents of apophenia in their findings.
